Pseudarthrosis of the clavicle. A case report

Congenital pseudarthrosis of the clavicle is a rare condition usually affecting the right side. The causation is unknown, but it is probably due to an environmental factor such as fetal position and excessive pressure from the subclavian artery. The embryology of the clavicle is discussed, and the differential diagnosis and treatment are described. A case occurring in a 12-year-old girl is reported.
